The CNE was closed during World War II and the grounds were used as a Training and Recruitment Centre.
This picture, taken at the CNE Bandshell, is of Prime Minister William Lyon Mackenzie King re-opening the fair in 1947, the year following the end of the war.
This would have been in the final of his three terms as Prime Minister of Canada (1921-1926; 1926-1930 and 1935-1948).
Mr King (1874-1950) was Canada's longest serving prime minister. He steered Canada through industrialization, much of the Great Depression, and the Second World War.
By the time he left office, Canada had achieved a greater independence from Britain and a stronger international voice.
Under his leadership, Canada also implemented policies such as unemployment insurance in response to industrialization, economic distress and changing social realities.
